ABSTRACT:
The specification discloses a wheelchair in which the seat, back and leg portions are so articulated and separately actuable, by power means, under control of the occupant, as to enable the occupant to assume any one of three positions, namely sitting, standing or reclining. Two separated leg support members are selectively actuable by the occupant to a horizontal leg-supporting position. Steering and forward and reverse propulsion controls accessible to the occupant are also provided, enabling the occupant to obtain substantially total mobility on level ground.
